CHARLES T. SCHOEN, OF PHILADELPHIA, AND JOHN M. HANSEN, OF BELLE- VUE,PENNSYLVANIA, ASSIGNORS TO THE PRESSED STEEL CAR COMPANY,

OF PITTSBURG, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 662,698, dated November27, 1906.

Application filed June 30, 1900. Serial No. 22,220. (No model.)

To ctZZ whom, it may concern:

Be it known that We, CHARLES T. SCHOEN, residing at Philadelphia, in thecounty of Philadelphia, and JOHN M. HANSEN, residing at Bellevue, in thecountyof Allegheny, State of Pen nsylvania,citizensof the United States,have invented a certain new and useful Improvement in Draft Rigging forRailway- Cars, of which the following is a full, clear,

'10 and exact description.

One object of the invention is to reduce the weight without impairingthe strength of the supports for the springs of draft-rigging, and incarrying out this part of the invention the draft-rigging sills are madeof metal, preferably pressed to shape, with embossments elevated fromtheir main plane and receiving the lugs which limit the endwisemovements of the springs, and these sills are embossed lon- 2ogitudinally between these elevations to reinforce or stiflfen them.

Another object of this invention is to provide rigging for the draw-barof a railwaycar which will effectively take up the strain both ofstarting and coming together of cars.

In carrying out this part of the invention use is made of springsarranged in tandem, or one at the end of another, with followerplatesand connections interposed, so that the shock will be transmitted fromone to another of the springs, and thus the car be relieved of unduestress in starting and coupling or otherwise coming together.

In the accompanying drawings, illustrating our invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a topplan view of portion of one end of a gondola or fiat-car. Fig. 2 is alongitudinal vertical section; and Fig. 3 is a section takensubstantially in the plane of line 3 3, Fig. 1.

The underframe may be of any approved construction, such as one of thestyles now in common use and made by the Pressed Steel Car Company.Between the end sill a and the bolster b are arranged the draft-riggingsills c peculiar to this invention. These sills are made aschannel-beamsthat is to say, with top and bottom flanges having boxedinends (Z-and their webs are provided with elevations e, between which arethe longitu- 5o dinal ribs f, projecting therefrom in the oppositedirection to the elevations. These elevations have riveted to them thelugplates g. Heretofore these lug-plates have been secured to flat websand were about one and a quarter inches thick in order to provide thenecessary bearings for the follower-plates. This thickness involves aconsiderable dead weight and expense. By elevating the Webs of thesills, as described, it is possible to obtain the requisite depth ofbearing with lug-plates of only seven-eighths-inch thickness, whereby isobtained a reduction of dead weight and economy of production.Moreover,the reduction in thickness of the lugs decreases the leverageon the rivets by which they are se cured in place.

The longitudinal ribs or embossments f serve to stiffen the sills at avulnerable point.

The embossing of the sills for both the ele- 7o vations and the ribs maybe effected simulta neously with the production of the sills when. madeof pressed steel, as we prefer to produce them.

The springs are arranged in tandem, and the outer springs it may be apair, while there is a single inner spring t' arranged end for end or intandem with the outersprings. The springs 71 are secured between thefollowerplates j 70, and each has a pin Z which abuts against a teat mon the outer follower-platej and projects through a hole inthe plate It.The spring '5 is arranged between followerplates at o, and there arepinsp which extend from the plate at through holes in the plate 0. Thepins Z therefore abut against the plate 0 and the pins 19 abut againstthe plate It, so that the strain placed upon either spring will betransmitted through pins and followerplates to the other. The springsand their 0 follower-plates are bound together and to the draw-bar g bythe strap 0", which is riveted at its ends to the draw-bar s.

We may use any number of springs within the limited space assigned inthe Master Car- Builders standard of spring-pocket, and, further, we donot limit our tandem arra ngement of springs to the peculiar sillsdescribed or the peculiarities of the sills to the arrangement ofsprings, since while these two fea-. tures of our invention are fittedto one another admirably they may be used separately.

A supporting-plate t, shaped to conform to the parts as seen in Fig. 3,is arranged beneath the springs and secured to the flanges of the sillsin a removable manner, as by bolt u; but other means may be used in thiscon nection for inclosing orsupporting the parts.

What we claim is- 1. A draft-rigging sill, made of pressed steel, havingtop and bottom flanges, boxedin ends, and a web, the web being embossedto provide elevations to receive the lug-plates, combined with suchlugplatcs, substantially as described.

2. A draft-rigging sill, havingintegral e1evations, combined withrelatively thin lugplates, substantially as described.

3. A draft-rigging sill, made of pressed steel, having top andbottomflanges, boxediuends, and a web, the web being embossed to formelevations to receive the lug-plates, and longitudinal hollow embossedribs projecting from the web of the sill in an opposite direction fromthe elevations and between said elevations, substantially as described.

4. The combination of a pair of followerplates, a pair of springsarranged between them, pins within said springs abutting against one ofsaid follower-plates and passing through the other, a second pair offollower-plates, a spring arranged between them in tandem with thefirst-named springs, pins abutting against the outermost follower-plateof this pair and extending through holes in its mate, and means forconnecting the parts with the draw-bar of a car, substantially asdescribed.

5. The combination of a pair of springs, follower-plates between whichthey are arranged, pins extending from one of the plates through theother, a spring and a pair of follower-plates between which it isarranged, and pins extending from the outer followerplate of thislast-mentioned pair through the inner plate, the pins of the two platesabutting against opposite plates interposed between the springs,substantially as described.

In testimony whereof we have hereunto set our hands in presence of thesubscribing witnesses.
